And we couldn't tease you with this, without showing you the video could we?

2. The World's Heaviest Building

This one is actually just pipped to the post for the largest building by surface area. Bucharest’s Palace of Parliament, also known as the House of the Republic or the People’s House, is the world’s SECOND largest building. That's after the Pentagon in the United States. 

However, what is really impressive is the weight of this thing.

The building is 12 stories tall, has 1,100 rooms and has a volume of 2.55 million cubic meters. 

It is constructed from 700,000 tonnes (1.5 billion lb) of steel and bronze combined with 1 million m³ (35.3 million ft³) of marble, 3,500 tonnes (7.7 million lb) of crystal glass and 900,000 m³ (31.7 million ft³) of wood.
